Description

[Technical Field]

[0001] The present invention relates to a card recycling system and a card recycling method used in a casino where a plurality of gaming tables are installed, to collect playing cards that have not been used at the plurality of gaming tables and generate a new playing card set consisting of a predetermined number of decks of playing cards. [Background technology]

[0002] In casinos, games using playing cards are played at gaming tables. A predetermined number of decks of playing cards (e.g., eight decks) are shuffled and packaged and provided to the gaming table. At the gaming table, the dealer opens the package and loads the shuffled playing cards into a card shooter. The dealer proceeds with the game by drawing playing cards one by one from the card shooter.

[0003] When new shuffled playing cards are loaded into the card shooter, a cut card is inserted slightly before the end of the shuffled playing cards. After multiple games have been played and cut cards have been drawn, the dealer replaces the shuffled playing cards in the card shooter while any unused playing cards remain in the card shooter. In other words, the shuffled playing cards after the cut card are discarded as unused cards (see, for example, Japanese Patent Application Laid-Open No. 2015-181948).

[0004] Therefore, it is planned to reuse these unused playing cards. These unused playing cards can be collected from multiple gaming tables and used to create a set of playing cards with a predetermined number of decks, thereby generating a new shuffled playing card set. Summary of the Invention [Problem to be solved by the invention]

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the embodiments described below are examples of how the present invention can be implemented, and the present invention is not limited to the specific configurations described below. When implementing the present invention, specific configurations corresponding to the embodiments may be appropriately adopted.

[0032] Figure 1 is a schematic diagram showing the overall configuration of a card reuse system according to an embodiment of the present invention. In Figure 1, thick arrows indicate the movement of playing cards, and thin arrows indicate the transmission of information. Note that information transmission may be either wired or wireless.

[0033] As shown in Fig. 1, the card reuse system 100 is installed in a casino having a gaming floor 1 and a backyard 2. In this embodiment, the backyard 2 is not limited to a general backyard, and may be any space that has security measures in place, such as restricting player entry and exit, in order to generate new playing card packages.

[0034] A plurality of gaming tables 11 are installed on the gaming floor 1. A plurality of card shooters 12 are installed on each gaming table 11 for drawing out shuffled playing cards one by one in a game. A code reader 13 is connected to each card shooter 12 as an identification information reading device for reading set identification information attached to a set of shuffled playing cards.

[0035] As described above, at each gaming table 11, when cut cards are drawn from the card shooter 12, even if some unused playing cards remain in the card shooter 12, a refreshing operation is performed in which these cards are replaced with new shuffled playing cards. At this time, the remaining playing cards are removed from the card shooter 12. In this way, the playing cards drawn from the card shooter 12 without being used are collected from the gaming table 11 into the backyard 2.

[0036] After each game, the playing cards used in the game are stored in a discarded card box (not shown in FIG. 1) installed on the gaming table 12. The used playing cards stored in the discarded card box are collected at an appropriate time in the backyard 2 and discarded via a predetermined route.

[0037] In the backyard 2, unused playing cards collected from multiple gaming tables 11 are collected, and playing cards constituting a predetermined number of decks (eight decks in this embodiment) are extracted, shuffled, and packaged. The packages of shuffled playing cards thus reproduced are transported back to the gaming tables 11 for reuse.

[0038] The backyard 2 is equipped with an extracting device 21 that extracts a predetermined number of playing cards from unused playing cards collected from the game table 11 without being used at the plurality of card shooters 12, a shuffling device 22 that shuffles the predetermined number of playing cards extracted by the extracting device 21, and a set generating device 23 that generates a new playing card set from the predetermined number of playing cards shuffled by the shuffling device 22 and packages the generated playing card set to generate a playing card package.

[0039] The extraction device 21 is equipped with a collected card information acquisition unit 211 that acquires information on the ranks and suits of the multiple playing cards collected from each of the multiple card shooters 12 and acquires information on the number of cards collected, a collected inspection device 212 that reads the ranks and suits of the playing cards actually collected from the card shooters 12 to the back hard 2 and counts the number of cards collected, and a non-extracted card information acquisition unit 213 that acquires information on the ranks and suits of playing cards that were not extracted from the multiple playing cards collected from the multiple card shooters 12 and acquires information on the number of cards collected.

[0040] The backyard 2 is also equipped with a management device 24 that manages the generation of playing card sets, and a storage device 25 that stores various data used by the management device 24. The management device 24, together with a collected card information acquisition unit 211, a collected card inspection device 212, and a non-selected card information acquisition unit 213, constitutes a card management system. In this card management system, the management device 24 determines whether the rank, suit, and number of cards information acquired by the collected card information acquisition unit 211 match the rank, suit, and number of cards inspected by the collected card inspection device 212. The management device 24 also determines whether the number of new playing card sets generated and the rank, suit, and number of cards information acquired by the non-selected card information acquisition unit 213 correspond to the rank, suit, and number of cards information acquired by the collected card information acquisition unit 211.

[0041] 2 is a schematic diagram showing the configuration of a card shooter according to an embodiment of the present invention. The card shooter 12 has a storage section 121 for storing shuffled playing cards C. The shuffled playing cards C stored in the storage section 121 are drawn out one by one through a drawer opening 122 for use in a game. The storage section 121 is provided with a mouse 123 that functions as a weight for pressing the trailing playing card C toward the drawer opening 122, and the mouse 123 always presses the leading playing card C against the drawer opening 122.

[0042] A drawn card inspection device 124 is provided near the drawing opening 122 to read the rank and suit of the playing card C being drawn and count the number of cards. The drawn card inspection device 124 is equipped with an ultraviolet lamp 1241 and a code detection sensor 1242. A binary code encoding the rank and suit is written on the surface of the playing card C (the side on which the rank and suit are written). This binary code is printed with ultraviolet luminescent ink that is invisible under natural light. The ultraviolet lamp 1241 irradiates ultraviolet light onto the binary code of the playing card C being drawn, and the code detection sensor 1242 scans the binary code luminescent by the ultraviolet light along the drawing direction of the playing card C.

[0043] The drawn card inspection device 124 reads the rank and suit of each playing card drawn and sends the read information to the control device 125, which functions as a remaining card inspection device. The control device 125 obtains the rank and suit information of the read playing card from the drawn card inspection device 124 and subtracts this information from the initially shuffled playing cards (8 decks) to determine the rank and suit of the playing cards C remaining in the card shooter 12, and further determines the number of remaining playing cards C.

[0044] FIG. 2 also shows a package 50 of shuffled playing cards. A barcode 51 representing identification information (package ID) of the package 50 is printed on the package 50. A code reader 13 for reading the barcode 51 on the package 50 is connected to the card shooter 12. The barcode 51 is read when new shuffled playing cards are loaded into the card shooter 12. The package ID, which is identification information of this package, corresponds to set identification information.

[0045] When an unused playing card C is removed from the card shooter 12, the control device 125 outputs information on the ranks and suits of all remaining playing cards at that time, as well as information on the number of cards, along with the set identification information of the playing cards.

[0046] 3 is a schematic diagram showing the configuration of an extracting device according to an embodiment of the present invention. The extracting device 21 includes a stocker 214 for stocking playing cards C collected from a plurality of card shooters 12, a draw roller 215 for drawing playing cards C one by one from the stocker 214, an extracting reader 216 for reading the binary codes of the rank and suit of the playing cards C drawn by the draw roller 215, and a sorting device 217 for sorting playing cards that make up a predetermined number of decks of playing cards C from playing cards that do not make up a predetermined number of decks of playing cards C based on the reading results of the extracting reader 216.

[0047] The extraction reader 216 has the same configuration as the withdrawal card inspection device 124 of the card shooter 12, and is equipped with an ultraviolet lamp 2161 and a code detection sensor 2162. The ultraviolet lamp 2161 irradiates ultraviolet light onto the binary code on the surface of the playing card C being transported by the withdrawal rollers 215, and the code detection sensor 2162 scans the binary code emitted by the ultraviolet lamp 2161 along the transport direction of the playing card C.

[0048] The sorting device 217 includes a rotating shaft 2171 and a guide blade 2172. The guide blade 2172 is rotated by the rotating shaft 2171, thereby rotating between an extraction position and a non-extraction position. When the guide blade 2172 is in the extraction position (a raised position in the example of FIG. 3), the playing cards C transported by the transport roller 215 pass through the guide blade 2172 and are sent to the extraction stocker 218 where the playing cards C are stocked to form a predetermined number of decks. When the guide blade 2172 is in the non-extraction position (a position where the tip of the guide blade 2172 touches the playing card C being transported in the example of FIG. 3), the playing cards C transported by the transport roller 215 are guided by the guide blade 2172 and are sent to the non-extraction stocker 219 as playing cards C that will not be used to form a predetermined number of decks of playing cards C.

[0049] The extraction device 21 further includes a control device 210 connected to the extraction reading device 216 and the sorting device 217. The control device 210 corresponds to the collected card information acquisition unit 211, the extraction control unit (collection inspection device) 212, and the non-collected card information acquisition unit 213 shown in Fig. 1. The extraction control unit 214 controls the sorting device 217 based on the reading result of the extraction reading device 216, thereby sorting playing cards C to be extracted and playing cards C not to be extracted in order to compose a predetermined number of playing cards.

[0050] 4 is a diagram showing an example of a data file including non-extracted card information according to an embodiment of the present invention. The extraction control unit 214 updates the data file D41 based on the reading result of the extraction reader 216. Specifically, when the number of extracted cards in the data file D41 for the rank and suit of a playing card C read by the extraction reader 216 does not reach the predetermined number of decks, i.e., eight, the extraction control device 212 controls the sorting device 217 to transport the playing card C to the extraction stocker 218, and also increases the number of extracted cards for the playing card C by one and decreases the missing number by one in the data file D41.

[0051] When the number of extracted cards in the data file D41 reaches the predetermined number of decks, 8, for the rank and suit of the playing card C read by the extraction reading device 216, the extraction control device 212 controls the sorting device 217 to transport the playing card C to the non-extraction stocker 219, and also increases the number of non-extracted cards of the playing card in the data file D41 by 1.

[0052] The extraction control unit 212 determines whether the number of extracted cards of all ranks and suits has reached eight each time a playing card C is processed, and outputs a completion report when the number of extracted cards of all ranks and suits reaches eight. At this time, the extraction stocker 218 will have eight playing cards C of each rank and suit, for a total of 416 playing cards C. These 416 playing cards are transported to the shuffling device 22. Note that, after a predetermined number of playing cards C have been collected in the extraction stocker 218, playing cards C that were not extracted by the extraction device 21 are returned to the stocker 214 to form the next predetermined number of playing cards.

[0053] Fig. 5 is a schematic diagram showing the configuration of a shuffling device according to an embodiment of the present invention. The shuffling device 22 is equipped with multiple tiers of sorting devices 221a to 221c. In the example of Fig. 5, the shuffling device 22 is equipped with three tiers of sorting devices 221a to 221c, but it may have four or more tiers. Since the multiple tiers of sorting devices 221a to 221c each have the same configuration, the following will only explain sorting device 221a, and explanations of sorting devices 221b and 221c will be omitted.

[0054] The sorting device 221a includes a rail 222a that is set upright in the vertical direction, a slider 223a that can move up and down along the rail 222a, a holder 224a that is fixed to the slider 223a and moves up and down together with the slider 223a, a sorting roller 225a that carries out the plurality of playing cards C held in the holder 224a one by one, and a shelf 226a that has a plurality of boxes for storing the playing cards C carried out from the holder 224 by the sorting roller 225a. In the example of Fig. 5, the shelf 226a includes six boxes, but the number of boxes is not limited to this.

[0055] The sorting device 221a further includes a control device (not shown), and the slider 223a and the sorting roller 225a are driven under the control of the control device. A random number is given to the control device, and the control device determines which box on the shelf 226a to store the item in based on the random number.

[0056] A set of a predetermined number of playing cards C (8 decks) extracted by the extraction device 21 is first loaded into the holder 224a of the first-stage sorting device 221a. When all the playing cards C have been sorted into any of the boxes, the playing cards C sorted into each box are stacked in order from top to bottom and loaded into the holder 224b of the second-stage sorting device 221b. By repeating this process, the set of a predetermined number of playing cards C (8 decks) is shuffled.

[0057] The playing cards C sorted into the multiple boxes on the final stage of the shuffling device 22 are stacked from top to bottom and transported to the set generating device 23. The set generating device 23 also functions as a packaging device that loads the shuffled 416 playing cards C into boxes, seals the boxes, and generates packages with shrink film. The package containing the set of shuffled playing cards C thus reproduced is transported back to the gaming table 11 and used in the game.

[0058] As described above, the set generating device 23 generates a new playing card set from a predetermined number of playing cards shuffled by the shuffling device 22. At this time, the management device 24 assigns set identification information for identifying the new playing card set to the new playing card set generated by the set generating device 23. The set generating device 23 also functions as a packaging device that loads the new playing card set into a card package. When the playing card set in the card package is loaded into the card shooter 12, the new playing card set is used on the gaming table 11.

[0059] When the set generation device 23 assigns set identification information to a new playing card set, the management device 24 associates this set identification information with the set identification information of the plurality of playing cards used to generate the new playing card set, which is acquired by the collected card information acquisition unit 211, and stores the associated set identification information in the storage device 25. For this purpose, the collected card information acquisition unit 211 of the extraction device outputs the set identification information of the playing card to the management device 24 every time an unused playing card from one card shoe 12 is supplied to the extraction device 21. The management device 24 accumulates the set identification information output from the extraction device 21 in this manner until a new playing card set is completed, and when a new playing card set is generated by the set generation device 23, refreshes the accumulated set identification information by associating all set identification information of unused playing cards used to generate the new playing card set with the set identification information of the new playing card set.

[0060] As described above, a new package of shuffled playing cards is generated using the playing cards C collected from the multiple card shooters 12, but the card reuse system 100 of this embodiment has a function to check whether there are any missing playing cards C due to loss, theft, etc. between the collection of the playing cards C and the generation of the new package. Such a check is performed under the control of the management device 24.

[0061] First, the card reuse system 100 has a function to confirm whether the playing cards C collected from the card shooters 12 of the multiple gaming tables 11 have been transported in their entirety to the extraction device 21 in the backyard 2. For this purpose, as described above, the control device 125 of the card shooter 12 outputs information on the ranks and suits of the remaining playing cards to be collected without being used, as well as information on the number of cards, along with the set identification information of the playing cards, and the collected card information acquisition unit 211 of the extraction device 21 acquires this information.

[0062] Fig. 6 is a diagram showing an example of a data file of collected card information according to an embodiment of the present invention. The card shooter 12 provides the extraction device 21 with the data file D61 shown in Fig. 6, and the extraction device 21 acquires this data file D61. The collected card information indicated by the data file D61 includes information on the ranks of the playing cards C to be collected, the number of cards by suit, and the total number of cards. The extraction device 21 provides the acquired collected card information to the management device 24, and the storage device 25 stores the collected card information in association with its set identification information.

[0063] As described above, the extraction control unit 212 of the extraction device 21 acquires the rank and suit of each of the collected playing cards C to determine which playing cards should be extracted. The extraction control unit 212, as a collection inspection device, outputs the number of cards by rank and suit read by the extraction reading device 216 and the total number of cards to the management device 24.

[0064] For this inspection, the stocker 214 of the extraction device 21 holds playing cards C for each card shooter 12 that has collected unused playing cards C, i.e., for each set identification information of the collected playing cards. The management device 24 checks whether the collected card information corresponds to the information on the number of cards by rank and suit and the total number of cards input from the collection inspection device 212 for each set identification information.

[0065] The management device 24 further checks whether the ranks and the numbers of the playing cards C that were not extracted by each suit when the extraction device 21 extracts a predetermined number of playing cards C are correct in light of the collected card information acquired by the collected card information acquisition unit 211. In other words, the management device 24 checks whether there is a shortage of playing cards C when the extraction device 21 extracts a predetermined number of playing cards C.

[0066] For example, when a predetermined number of playing cards are extracted from ten collected playing cards, the management device 24 checks whether the number of cards per rank and suit obtained by subtracting the number of cards (8 cards) per rank and suit of the predetermined number of decks (8 decks) from the information obtained by adding up all the collected card information related to these ten collected playing cards stored in the memory device 25 matches the number of cards per rank and suit of the multiple playing cards C that the extraction control unit 212 determined not to have been extracted.

[0067] In other words, the management device 24 checks whether the number of cards per rank and suit, which is the sum of the number of cards per rank and suit (8 cards each) of the extracted predetermined number of decks (8 decks) and the number of cards per rank and suit of the multiple playing cards C that were determined not to be extracted, matches the total of the collected card information related to multiple collections acquired by the collected card information acquisition unit 211.

[0068] This allows checking whether there is a shortage when sorting the plurality of playing cards C collected by collecting multiple times into extracted / non-extracted cards to form a predetermined number of decks of playing cards C.

[0069] For this inspection, the non-extracted card information acquisition unit 213 acquires information on the rank and number of playing cards C determined to be non-extracted by suit based on the extraction decision made by the extraction control unit 212 as non-extracted card information, and outputs this to the management device 24.

[0070] When a predetermined number of playing cards C are extracted, the management device 24 checks whether the collected card information input from the collected card information acquisition unit 211 corresponds to the non-extracted card information input from the non-extracted card information acquisition unit 213.

[0071] 7 is a flowchart of a card recycling method according to an embodiment of the present invention. In the card recycling method, first, unused playing cards are collected from the card shooter 12 into the backyard 2 (step S71). Then, the extraction device 21 extracts a predetermined number of decks of playing cards from the collected unused playing cards, and outputs set identification information of the unused playing cards to the management device 24 (step S72). Next, the shuffling device 22 shuffles the predetermined number of decks of playing cards extracted by the extraction device 21 (step S73).

[0072] The set generating device 23 generates a new playing card set from the predetermined number of playing cards shuffled by the shuffling device 22, and assigns set identification information to the new playing card set (step S74). Then, the management device 24 associates the set identification information acquired from the collected card information acquiring unit 211 with the set identification information assigned to the new playing card set by the set generating device 23, and stores them in the storage device 25 (step S75).

[0073] In the above embodiment, the non-extracted card information acquisition unit 213 acquires information on the rank and suit of the playing card C that has been determined not to be extracted by the extraction control device 212 as non-extracted card information. However, instead, the non-extracted card information acquisition unit 213 may acquire non-extracted card information by reading the ranks and suits of a plurality of playing cards C stocked in the non-extraction stocker 219.

[0074] Furthermore, in the above embodiment, the management device 24 checks whether the collected card information corresponds to the non-extracted card information when a predetermined number of playing cards C are extracted. Alternatively, the management device 24 may check, for each collection (i.e., for each set identification information), whether the sum of the number of playing cards C extracted by the extraction device 21 by rank and suit and the number of playing cards C not extracted by rank and suit corresponds to the collected card information.

[0075] In the above embodiment, the management device 24 determines whether the information on the number of cards for each rank and suit acquired by the retired card information acquisition unit 211 matches the number of cards for each rank and suit inspected by the retired card inspection device 212, and also determines whether the number of new playing cards in the generated set and the number of cards for each rank and suit acquired by the non-selected card information acquisition unit 213 correspond to the number of cards for each rank and suit acquired by the retired card information acquisition unit 211. However, instead of this, the management device 24 may only determine whether the numbers match. That is, the management device 24 may determine whether the information on the number of cards acquired by the retired card information acquisition unit 211 matches the number inspected by the retired card inspection device 212, and also determine whether the number of new playing cards in the generated set and the number of cards acquired by the non-selected card information acquisition unit 213 correspond to the number acquired by the retired card information acquisition unit 211.

[0076] In the above embodiment, the management device 24 checks whether there is a shortage between collection and playback by checking the rank and suit of the playing cards C and their total number, but the management device 24 may check whether there is a shortage by checking the rank and suit of the playing cards C, or the management device 24 may check whether there is a shortage by checking only the number of playing cards C.

[0077] In the above embodiment, the cards drawn one by one by the card shooter 12 are read and the reading results are subtracted from the initially shuffled playing cards to obtain information on the suits, ranks and number of the remaining (recovered) playing cards as collected card information. However, instead of this, collected card information may be obtained by a collected card reading device that reads the playing cards to be collected, or a discarded card reading device that reads discarded cards that have been used in the game and discarded.

[0078] The collected card reader reads the rank and suit of the playing cards while feeding the collected playing cards one by one, using the same configuration as the drawn card inspection device 124. The card shooter 12 may also be used as the collected card reader. In this case, the card shooter 12 is set to the collected card reading mode, and the playing cards to be collected are drawn one by one, and the drawn card inspection device 124 reads the rank and suit.

[0079] When reading discarded cards, a discard slot is provided on the gaming table 11, and the rank and suit of the playing card inserted into the discard slot after being used in the game are read using the same configuration as the drawn card inspection device 124.

[0080] In the above embodiment, the rank and suit information is printed on the playing cards in the form of a binary code using ultraviolet luminescent ink, but instead of ultraviolet luminescent ink, it may be printed using ultraviolet absorbing ink that becomes visible when irradiated with infrared light. Also, instead of printing using these invisible inks, the rank and suit marks printed on the playing cards may be photographed and the rank and suit may be read by image analysis.

[0081] In addition, in the above embodiment, the management device 24 determines whether or not the number of new playing card sets generated and the information on ranks and suits and the information on the number of cards acquired by the non-selected card information acquisition unit 213 correspond to the information on ranks and suits and the information on the number of cards acquired by the collected card information acquisition unit 211. However, instead of this, the management device 24 may determine whether or not the number of new playing card sets generated and the information on ranks and suits and the information on the number of cards acquired by the non-selected card information acquisition unit 213 correspond to the information on ranks and suits and the information on the number of cards inspected by the collected card inspection device 212.

[0082] In the above embodiment, the predetermined number of decks of playing cards extracted by the extracting device 21 are shuffled by the shuffling device 22 and then packaged by the packaging device 23, but shuffling by this shuffling device may be omitted. That is, since the unused playing cards to be collected have already been shuffled, even when such unused playing cards are collected from the multiple card shooters 12 and a new set of the predetermined number of decks of playing cards is extracted, the randomness of the order of the playing cards is considered to be maintained. Therefore, the shuffling device 22 may be omitted.

[0083] In addition, in the above embodiment, the card management system had a function of checking whether any unused playing cards were lost before collecting and reusing them, but this specification also discloses as an invention a card reuse system that does not have such a function.

[0084] In addition, in the above embodiment, in order to check whether the ranks, suits and number of playing cards actually collected in the back yard match the collected card information, a configuration is used in which the extraction device 21 reads the ranks and suits to extract a predetermined number of decks of playing cards. However, instead of this, a collection inspection device may be provided in the back yard, separate from the extraction device 21, to check whether the ranks, suits and number of playing cards actually collected in the back yard match the collected card information.

[0085] In the above embodiment, the extraction device 21 is configured to extract only one set of a predetermined number of decks of playing cards, but instead, the extraction device 21 may be configured with multiple stages including a first stage and a second stage. In this case, in the second stage, a predetermined number of decks of playing cards are extracted from playing cards that were not extracted in the first stage as playing cards that do not constitute the predetermined number of decks of playing cards.

[0086] Furthermore, in the above embodiment, the extracting device 21 performs the extraction process for each set of multiple playing cards collected from one card shooter 12, but the extraction process may also be performed by simultaneously placing multiple playing cards collected from multiple card shooters 12 into the stocker 214. Furthermore, multiple playing cards newly collected from card shooters 12 may be added to the stocker 214 while the extracting device 21 is performing the extraction process.

[0087] Furthermore, the extraction device 21 may have a function to inspect the quality of the playing cards as they are processed one by one, and may not extract playing cards whose quality does not meet a predetermined standard. The quality of the playing cards inspected here may be, for example, whether or not they are bent, scratched, or have oily stains (from fingers), etc.

[0088] In addition, in the above embodiment, the non-extracted card information acquisition unit 213 acquires information on the ranks and suits of the non-extracted playing cards and information on the number of cards by calculating by subtracting the ranks and suits of the extracted playing cards from the ranks and suits of the collected playing cards. However, instead of this, information on the ranks and suits of the non-extracted playing cards and information on the number of cards may be acquired by using a device that reads the ranks and suits of the non-extracted playing cards.

[0089] In the above embodiment, a new playing card set is provided to the card shooter 12 in the form of a package, and the package is opened to remove the playing card set and load it into the card shooter 12. Alternatively, the card shooter 12 may employ a cartridge system. In this case, the storage section 121 of the card shooter 12 is a cartridge that is detachable from the card shooter 12, and the cartridge is replaced when refreshing. For this reason, a new playing card set is provided to the gaming table 11 in a cartridge state, and when refreshing, the cartridge that was previously attached to the card shooter 12 is replaced with a cartridge that contains the new playing card set.

[0090] The cartridge is provided with a locking mechanism to prevent playing cards from being removed or added during transport. The cartridge is unlocked by the locking mechanism when it is attached to the card shooter 12. When unused playing cards are transported to the extraction device 21 in the backyard 2, a cartridge is used, and in this case too, the cartridge is locked by the locking mechanism during transport. The set generation device 23 loads a newly generated playing card set into a cartridge instead of packaging it, and locks the cartridge's locking mechanism.

[0091] Just as the set identification information is printed on the package, the set identification information is also given to this cartridge. Note that in order to enable the cartridge to be used repeatedly, the set identification information is given to the cartridge in a rewritable format. For example, a piece of paper on which the set identification information is printed is attached to the cartridge.

[0092] Furthermore, in the above embodiment, when unused playing cards are collected from the card shooter 12, the set identification information of the unused playing cards is provided from the card shooter 12 to the extraction device 21, but instead of this, or in addition to this, shooter identification information for identifying the card shooter 12 may be provided from the card shooter 12 to the extraction device 21.

[0093] In this case, instead of or in addition to the set identification information acquired by the collected card information acquisition unit 211, which is the set identification information of the plurality of playing cards used to generate the new playing card set, the management device 24 stores in the storage device 25 the shooter identification information acquired by the collected card information acquisition unit 211, which is the shooter identification information of the plurality of card shooters who collected the plurality of playing cards used to generate the new playing card set, in association with the set identification information of the new playing card set.

[0094] Furthermore, in the above embodiment, the management device 24 associates the set identification information of the new playing card set with the set identification information of a plurality of playing cards that was acquired by the retired card information acquisition unit 211 and that was used to generate the new playing card set. However, instead of this, the management device 24 may associate the set identification information of the new playing card set with the set identification information of a plurality of playing cards that was acquired by the retired card information acquisition unit 211 and that was potentially used to generate the new playing card set.

[0095] That is, in the above embodiment, a plurality of unused playing cards collected from one card shoe 12 are supplied together to the extraction device 21, and at that time, the extraction device 21 reports the set identification information of the plurality of unused playing cards to the management device 24. The management device 24 accumulates the set identification information of the unused playing cards used in a new playing card set until a new playing card set is generated by the set generation device 23, and when a new playing card set is generated by the set generation device 23, all of the set identification information accumulated up to that point is associated with the set identification information of the newly generated playing card set. Alternatively, a looser management system may be used.

[0096] That is, without strictly managing the set identification information of unused playing cards supplied to the extraction device 21, the management device 24 may associate, for a certain period (for example, one day), the set identification information of unused playing cards supplied to the extraction device 21 with the set identification information of a new playing card set generated by the set generation device 23 for that certain period. Alternatively, the management device 24 may associate, for a certain period, the set identification information of unused playing cards collected in the backyard 2 with the set identification information of a new playing card set generated by the set generation device 23 for that certain period. That is, an unused playing card of a set identification information associated with the set identification information of a new playing card set generated by the set generation device 23 may not necessarily be included in the new playing card set. Alternatively, a new playing card set having set identification information associated with the set identification information of an unused playing card may not necessarily include the unused playing card.

[0097] Furthermore, the management device 24 may associate the set identification information of the new playing card set with the shooter identification information acquired by the collected card information acquisition unit 211, which is the shooter identification information of the multiple card shooters 12 that collected multiple playing cards that could have been used to generate the new playing card set.
